You've heard the old adage that "It's not about the destination; it's about the journey." For cloud migrations and modernizations, however, it's all about the destination. Picking the right destination or cloud platform for your workload can make all the difference between success and failure in terms of achieving your cloud migration objectives. This session covered the considerations, technologies and approaches that can be used to pick the right cloud targets and achieve the right balance between migration and modernization.

11. Five questions to ask yourself about
the destination
11Think 2019 / Session 3266 / February 14, 2019 / © 2019 IBM Corporation
1. What workloads and services to move to
Cloud?
2. What type of application modernization
should be applied?
3. What location, degree of sharing, and
delivery model?
4. What degree of development and
operations modernization are possible?
5. How will I integrated a new delivery and
operating model into my existing
landscape?

12. Best practices:
• Prioritizing workloads
• Dividing journey into bite size chunks
• Tying workload selection to business value
• Iteratively doing discovery
Anti-pattern:
• Selecting all workloads at once
12Think 2019 / Session 3266 / February 14, 2019 / © 2019 IBM Corporation
Determining what to move to Cloud
– What subsets of workloads within the current estate
would benefit from being moved to the Cloud in the
next 3-12 months?
– Considerations and tradeoffs
• Prioritization of workloads is key at this stage
• Current pain points such as aging hardware, capacity
issues, out of date software or hardware, need
for increased agility, upcoming major releases,
addressing compliance issues, improved resiliency
• What would be easiest to move and modernize:
• Apps with few(er) external dependencies on other
systems or data
• Workloads that are less critical (at least for initial
migrations)
• Packaged software available in the cloud (SaaS),
• Urgency / time to value
Method, tools and techniques
• Cloud Advisory Services Method
• RVTools
• IBM Service Platform With Watson Technical
Health Check
• RiscNetworks CloudScape
• IBM Services for Multicloud Management
• Planning application (Application Screener)

13. Best practice:
• Show incremental progress before tackling
more ambitious projects
• Consider the business case and balance with
existing technical debt
Anti-pattern:
• Aiming to modernize all workloads at once
13Think 2019 / Session 3266 / February 14, 2019 / © 2019 IBM Corporation
Determining level of modernization
– What level of modernization should be applied
to the workload?
– Considerations and tradeoffs
• Choose between several modernization options:
• As-is VM moves
• VMs described as IaC,
• Managed Cloud Services (e.g. Cloud Foundry),
• Containers with microservices
• Serverless
• Urgency vs. affordability; desired timeline
• Choice of modernization technique may vary by
application or even workload within application
• Skills
Methods, tools and techniques
• Migration patterns from Cloud Innovate
• Data from prior migration projects

14. Best practice:
• Use a fact-based decision to determine where
to land workload
Anti-pattern:
• Picking too many landing pads without
considering operational impact
14Think 2019 / Session 3266 / February 14, 2019 / © 2019 IBM Corporation
Determining where to land workload
– Where should the workload land in the Cloud?
– Considerations and tradeoffs
• Multiple choices for transformation: IBM Cloud Private,
IBM Cloud Public, VMware mission critical landing pad,
OpenWhisk, Azure, AWS ….
• Each landing pad has it’s unique performance, scalability,
compliance, cost …
• Decision is frequently linked to the nature of existing
workload, service levels, data gravity
• Fact-based approach to selecting the right place
to run the workload.
Methods, tools and techniques
• IBM Services for Multicloud Management
• Planning application (Cloud Compare)

15. Best practices:
• Focus on those applications that allow for full
transformation of people, process, and tools.
• Integrate Operations into Development
employing an SRE model.
Anti-patterns:
• Assuming this is a DevOps tools and technology
selection problem only.
15Think 2019 / Session 3266 / February 14, 2019 / © 2019 IBM Corporation
What degree of development and operations
modernization are possible?
DevOps transformation can provide radically improved velocity
for application innovation and operational efficiency.
• It is important to understand the architecture and design
principals for Cloud Native applications.
• Technologies like Containers and Kubernetes make life much
easier for the Cloud Native developer, however you must
understand the principals to leverage them effectively.
• Take the Twelve-Factor Methodology Seriously.
• There is no such thing as Sort-of Immutable.
• Infrastructure is treated as Cattle vs. Pets.
• Treat Infrastructure as Code and manage in your single
source code management system (e.g. Git).
• The “Ops” in DevOps can’t be overlooked and requires a
“shift-left” in operations from Day-2 into Development.
DevOps is a culture change across people, processes and tools
to both applications and operations teams.

16. Methods, tools and techniques
IBM Services for Multicloud Management
Best practice:
• Provide consistency and unification through
federation across both the traditional and new
service management models.
Anti-pattern:
• Attempting to apply a single service
management model to all.
16Think 2019 / Session 3266 / February 14, 2019 / © 2019 IBM Corporation
How will I integrated a new delivery and
operating model into my existing landscape?
• Dedicate resources to the optimization and automation
of legacy apps and IT, driving towards cloud native and
DevOps practices (e.g. Infrastructure as Code).
• Dedicating resources to the development of new and
transformation existing applications to cloud native and
DevOps and avoid compromises.
• Integrate new cloud consumption and management models
(e.g. self-service) with traditional services management
models (e.g. approvals, ticket based tracking, etc.)
• Leverage a Cloud Management Platform (CMP) that
embraced a Dual Speed (Multi-Modal) IT model.
Embrace Multi-Modal IT... Co-Existence between ore
traditional enterprise service management and DevOps will
be a reality for the foreseeable future .
